A research question must... Select one: O be something you can make a claim about.
O be answered in a single word.
O be something you know a lot about.
O be really hard to find information about.

answer: b

explanation:

the answer is a)   a sentence of death costs the state "almost three times as much as a sentence of life in prison" (delon 147)

the correct answer is 4) infinitive phrase with a direct object

the explanation is that the infinitive phrase, "to with the younger children", functions as the object. it means the thing that the subject does.

1) no infinitive is incorrect because there is an infinitive verb in the sentence.

2) an infinitive only is incorrect because it is not in isollation. it is part of an infinitive phrase.

3) infinitive phrase with a subject is incorrect because in this example the infinitive phrase does not function as the subject doing the action of the sentence.

the correct answer is b.
